[gem5-users] Single Step Support in x86

[Deepak Mohan via gem5-users]

Hi,
Is single stepping supported in gem5 x86 (by setting the Trap Flag in
RFLAGS register) ? I was working with an educational OS that runs on gem5,
and was trying to add a single step feature to it. But when I set the Trap
flag in the RFLAGS saved on stack and called IRETQ instruction, it seems
that the Trap Flag is not set in the RFLAGS register. Can anyone provide
some information on this, like where to look in the gem5 source code to get
a better understanding.

Thanks,
Deepak Mohan
